The fruit-flavored gelatin you loved as a kid could be a treatment for your joint issues. A 1998 study at Ball State University found that athletes with knee pain who consumed a gelatin supplement called Knox NutraJoint experienced a significant reduction in pain compared to a placebo. Gelatin is made from animal collagen, an essential structural protein found in bones, tendons and other tissues. Gelatin is especially high in proline and glycine, two amino acids that play an important role in collagen formation, which may explain its positive effect on joint problems.

Step 1

Pour 6 to 8 oz. of fruit juice, such as orange or apple, into a glass.

Step 2

Add 1 scoop of Knox NutraJoint or 11 g of powdered gelatin to the glass of juice.
